There are 52 weeks in a year that's 365 days but when you work the math it doesn't come out right 7X52=364?

Answer 1

A year is about 365.25 days (that's including a leap year evey fourth year; there is not a leap year if the year ends in 00 unless it is divisible by 400). Of course, there are also the occasional leap seconds that get thrown in to keep the math right.

If you want to get real wacky, take a look at a lunar calendar like the Hebrew one. There's a 19-year cycle that includes various leap days and even a leap month in order to make sure that your planting seasons stay where they should.

Back to our "year", if you multiply an hourly salary by 2000, that's about a yearly salary assuming 40 hours a week and 2 weeks unpaid, but again, that's just an approximation.

Answer 2

A lot of people are reading this question wrongly and giving incorrect answers so just to clarify: There are 365.25 days in a year. 365 in a non leap year and 366 in a leap every (every fourth year there is a 19th day in February) We say 52 weeks because it's convenient even though it does only account for 364 days. Missing 1 day in a normal year and 2 days in a leap year. If you count up the days in all the months of a non leap year you will see there are 365 Jan 31 Feb 28 Mar 31 Apr 30 May 31 Jun 30 Jul 31 Aug 31 Sept 30 Oct 31 Nov 30 Dec 31 Equals 365 :)

Answer 3

The year is actually slightly less than 365-1/4 days long. So most years are 365 days, and usually every 4th year is 366 days. This gives you 52 full-seven day weeks, but you also have a day or two left over. In fact, if you check a 2006 calendar vs a 2007 calendar, you will find that the day of the week for a given calender day is one day later in 2007 than in 2006.

Answer 4

every four years is a leap year.

add the number in each and there 365 or 366, which actually 365.25, because one of four years are leap year.

7 x 52 = 364 + 1= 365 + 1= 366

Answer 5

364 days/year = 30 1/3 days/month

If there were exactly 30 1/3 days in a month, there would be 364 days in a year.

But

there are 7 months with 31 days => 7*(31 - 30 1/3) = 14/3 days

there are 4 months with 30 days => 4*(30 - 30 1/3) = - 4/3 days

there is 1 month with 28 days => 1*(28 - 30 1/3) = - 7/3 days

Adding all = 14/3 - 4/3 - 7/3 = 3/3 = 1 day

Because of the discrepancies in the number of days in a month, there is 1 day plus 364 days in one year.

Answer 6

There are actually 365.25 days in a solar rotation. Thus the need for a leap year. That's an approximation, because every 100 years there is not a leap year, but in the 400th year there is. Your conudrum is from the fact there is one more day in a year than will fill in equal number of weeks. This is why each year starts on a different day.

Answer 7

31+28+31+30+31+30+31+31+30
+31+30+31=365 days for a regular year.

31+29+31+30+31+30+31+31+30
+31+30+31=366 days for a leap year.

Answer 8

52 weeks and 365 days are just approximations of the solar year.

Answer 9

There's actually like 365.241 days in a year.

Every fourth year is a "leap" year which gets an extra day in February.

Unless that year is divisible by 100. Then it doesn't get that extra day.

But if that year is divisible by 1000, it gets to ignore the every 25th leap year (every 100 years) doesn't get one rule, so it does have the extra day.

Answer 10

it is because febuary loses 1 day every year
it is a leap year
